WEEKLY
1. Examine the inner compartment and see if frost
formation is more than 1 /4" (6 mm). If so,
DEFROST the appliance as described earlier (see
page 10).
If it is observed that Defrosting is required to be
done each week:
a) Examine the rubber seal on the lid, if it sits
properly. Any gap between the cabinet and seal
can be checked by placing a visiting card between
them. The card should resist being pulled out
freely. If the card can be pulled out freely, there
exists a gap. Such gap will allow outside air to go
in and form frost early. In such cases the lid should
be adjusted or the seal should be changed.
b) Restrict and reduce frequency of opening the
appliance. Open only when absolutely necessary.
MONTHLY
1. Clean the compressor compartment:
a) Put off the switch, if any, and take out the plug from
the wall socket.
